QResearch Databases – Governance – Coverage Examples of studies – QDiabetes -risk of complications – Hypoglycaemic drugs – VTE & oral contraceptive Questions Overview
Set up in 2002 by EMIS and University of Nottingham Support from EMIS, RCGP, BMA, SAPC REC > 1000 practices EMIS Web > 20 million patients (current and historical) Coded longitudinal data for 20+ years – Socio-demographics – Diagnoses – Clinical values & tests – Prescription data – Consultation data No patient identifiers – pseudonymised-at-source Now linked to HES, ONS, Cancer register QResearch
Provides oversight for QResearch Principles and policy for access to data Oversees communication with & benefits back to patients & practices Includes professional & patient representation – EMIS & EMIS NUG – Patient advisers – RCGP & SAPC – BMA – UoN QResearch Advisory Board

Risk of Complications in Patients with Diabetes
Risk of diabetes complications Diabetes associated with micro & macrovascular complications Intensive control risk factors lowers incidence microvascular complications. Most patients little idea of risk – over-estimate risk of complications – over-estimate benefits of treatment Amputation & blindness most feared & most affect quality of life Ba Background
Aims To quantify risk of complications in people with type 1 or type 2 diabetes – Amputation – Blindness – Heart failure – Kidney failure ( – Cardiovascular disease ( Better information for patients to inform decisions Better tools to risk stratify patients to match interventions to level of risk Aims
Methods Cohort study people with type 1 & type2 diabetes Follow up over 15 years Measure risk factors at baseline Measure outcomes (amputation/blindness/CCF) Develop risk prediction algorithms ‘Validate’ tools to make sure it works well CCF results published BMJ open Amputation/blindness in press BMJ Methods
Chronic kidney disease Atrial fibrillation Heart failure Peripheral vascular disease Rheumatoid arthritis Blood pressure treatment Age Sex Ethnic group Deprivation Smoking status Type of diabetes Duration of diabetes HBA1C Cholesterol/HDL Systolic blood pressure Clinical values Comorbidity Demography/ lifestyle Key Factors in Model

Limited trial evidence of effectiveness of hypoglycaemic drugs on outcomes Most focus on surrogate measures HBA1C Using QResearch linked data to look at key outcomes Heart disease Kidney disease Blindness Amputation Cancer New study on risks/benefits hypoglycaemics Gliptins Insulin Other agents Sulphonyl ureas Metformin Glitazone
Risk of Thrombosis in Women taking the Oral Contraceptive Vinogradova, Y Coupland C, Hippisley-Cox J. BMJ 2015
Introduction Exposure 9% worldwide, 18% developed countries, 28% UK Effective for preventing pregnancy Earlier COC Norethisterone (1960s) Levonorgestrel (1970s) Newer COC Norgestimate (1980s) Desogestrel (1980s) Gestodene (1980s) Drospirenone (2000s ) Aim: Examine risk of VTE for most common types of the Pill taking account of other patient characteristics COC – combined oral contraceptives Risk of VTE and Oral Contraceptive
Methods: Study design Nested case control study Study period Jan 2001– Dec 2013 Aged 15 – 49 At least 1 year of records Up to 5 controls matched by –Age, practice –Calendar year Exclusions: –previous VTE/ AC therapy, sterilisation, pregnancy Methods: study population
Methods: Exposure to the Pill Terms of use Current use (within 28 days ) Short term (up to 84 days) Long term (more than 84 days) Exposure to only one current COC Past use (29 to 365 days) Types of progestogen Norethisterone Levonorgestrel Norgestimate Desogestrel Gestodene Drospirenone Cyproterone Other contraceptives Progestogen only pill Non-oral contraceptives Dose of oestrogen 20µg 30µg or more Methods: exposure to COP
Methods: Confounders Chronic conditions (cancer, congestive cardiac failure, varicose veins, congestive cardiac disease, rheumatoid arthritis, Systemic lupus erythematosus, renal disease, asthma, Chronic obstructive pulmonary disease, Crohn’s disease or colitis, coagulation disturbances) Immobilisation (last 6 months) (acute infection, surgery, hospitalisation, fracture) Body mass index, smoking, alcohol, ethnicity Polycystic ovary syndrome Methods: things we can take into account

Numbers needed to harm Progestogen typeNumbers needed to harm over 1 year Extra cases per treated per year Norethisterone Levonorgestrel Norgestimate Desogestrel Gestodene Drospirenone Cyproterone Note risk still lower than VTE risk during pregnancy Numbers needed to harm
Conclusions The largest study providing reliable comparable findings with earlier large-scale studies Completely independent of pharma Based on British population and prescribing practice Able to drill down to level of individual drug Newer drugs higher risks than older drugs Drugs containing gestodene, desogestrel, drospirenone & cyproterone higher risks than levonorgestrol or norgestimate Conclusions
Drug-safety projects Risk of GI bleeding in patients taking Cox-2 inhibitors or NSAIDS Risk of myocardial infarction in patients taking Cox-2 inhibitors or NSAIDS. The effect of statins on mortality in patients with ischaemic heart disease Risk of pneumonia in patients taking statins: Unintended effects of statins in men and women Exposure to Cox-2 and NSAIDs and risk of Cancer Risk of colorectal cancer in patients taking statins and NSAIDs Exposure to Statins and risk of common cancers Risk of cancer in patients with diabetes prescribed glitazones Risk of cancer with bisphosphonates Antidepressant use and the risk of adverse outcomes in older people Safety of smoking cessation treatments Antipsychotic medication and risk of thromboembolism Risk of bleeding in patients prescribed NOACs (novel anticoagulants) Other Drug Safety Studies
